Auth services provide other services user authentication and identification information.
The central component is the :doc:`Auth Proxy <proxy/index>` which has the :doc:`authentication interface <proxy/interface>`. Auth Proxy works as a proxy between services and authentication sources. :doc:`Auth Sources <source>` have the actual user identity information and perform the credential checks.
User attributes can be queried from the :doc:`Auth Data service <data/index>`.
